The testo 540 luxmeter: small, handy, precise
The testo 540 luxmeter is an entry-level model and has been specially developed for quick spot measurements at workplaces, in offices and stores. The sensor is modeled on the spectral sensitivity of the human eye and is ideal for assessing illuminance.
The measured values are easy to read on the illuminated display and the minimum and maximum values are shown at the touch of a button. The hold function makes it easy to read off the measured values. The handy, easy-to-use lux meter can be safely stowed away until the next measurement thanks to the protective cap supplied.
